From Stretcher to Dashboard: The Trauma Patient as a Data Source

Consider what happens in the first hour of a major trauma case. A patient is treated at the scene by para-medics – immediate care is given and vital signs are recorded.  This continues in the ambulance or helicopter. A paramedic calls ahead to the hospital. A trauma team assembles to accept the patient, maybe reads a paper handover form, and begins their own assessment from scratch.

In that “golden hour”, an extraordinary amount of data could be generated - temperature trajectory, blood pressure, oxygen saturation trends, physiological status and response.  Yet, today, almost none of this data is captured in a form that can be stored, shared, learned from or used for more effective triage. At the hospital door, to all intents and purposes, it disappears, even if it was recorded. 

This is the data that could help the trauma team treat the patient faster and more effectively. It is also the data that could save the next patient with similar issues.  Yet we throw it away. That is not a data problem - it is a leadership and system design problem.

What the Research Says

The evidence on information loss in trauma handovers is consistent and damning. A landmark study of 96 handovers at a Level I trauma centre found that only 72.9% of clinical information transmitted by pre-hospital teams was received and documented by hospital staff — in the controlled setting of a direct, face-to-face handover. The losses were concentrated precisely in the data that matters most:

·       35.7%	of recorded pre-hospital hypotension episodes received by the hospital team
·       45%	of Glasgow Coma Scale scores transmitted pre-hospital documented in-hospital
·       26.5%	of pulse rate readings transmitted by paramedics captured in hospital records

A separate study found that relying on memory alone retains 33% of handover information. A standardised written form raises that to 99%. The technology is not the constraint — a simple piece of card triples retention. What is missing is the system / process that makes data capture the accepted norm rather than an additional burden.  Individuals do their best in spite of the lack of formalised process – eg. the paramedic who writes vital signs on a latex glove that can travel with the patient into the hospital.  This is not a failure of individual professionalism. It is a failure of system design.

Why Technology Alone Won't Fix It

In Transform!, we trace the consistent pattern that emerges when organisations deploy technology without first addressing the human and organisational architecture that determines whether it can actually be used.

The UK Post Office Horizon scandal is a painful recent example: a system deployed at scale without adequate testing against real operational conditions, whose failures were blamed on the people using it rather than the system itself.

Pre-hospital data follows the same pattern. The UK air ambulance network operates across 21 independent charities, each with its own data systems and governance structures. Several digital capture initiatives have been piloted but none have become the standard — not because the technology was wrong, but because shared governance, aligned incentives, and the will to standardise across independent organisations were not established first.

What the Data Could Tell Us — If We Kept It

A better dataset of pre-hospital trauma transfers would answer questions that materially change patient outcomes - at what point in a temperature trajectory does coagulopathy become probable? Which pre-hospital vital sign combinations most reliably predict resuscitation requirements on arrival? 

A governance framework that captured and shared such data would produce evidence of a different order entirely: not 'this addresses a known problem' but 'this changes specific physiological trajectories in ways that correlate with outcomes.' That is the evidence that changes procurement decisions.

The tools exist – but governance frameworks, data standards, and cross-organisational will to use them do not yet. That is a leadership problem which we will discuss on 26 May.
